Hi, everyone! 
First of all this is my first post in this great site of information.
I found many solutions in here like filtering data values, sorting and gathering array values in excel.
Ok, here I want to ask for some help.
The problem is getting smallest date values of C904.
In my excel file worksheet "events" I constructed array formula with SMALL function and it doesn't return smallest January date value of C904 and also skips some smallest February date values.
So, I inserted my excel file link.
